| Abstract | Temperature has a strong influence on integrated circuit (IC) performance, power consumption, and reliability. However, accurate thermal analysis can impose high computation costs during the IC design process. We analyze the performance and accuracies of a variety of time-domain dynamic thermal analysis techniques and use our findings to propose a new analysis technique that improves performance by 38–138x relative to popular methods such as the fourth-order globally adaptive Runge-Kutta method while maintaining accuracy. More precisely, we prove that the step sizes of step doubling based globally adaptive fourth-order Runge-Kutta method and Runge-Kutta-Fehlberg methods always converge to a constant value regardless of the initial power profile, thermal profile, and error threshold during dynamic thermal analysis. Thus, these widely-used techniques are unable to adapt to the requirements of individual problems, resulting in poor performance. We also determine the effect of using a number of temperature update functions and step size adaptation methods for dynamic thermal analysis, and identify the most promising approach considered. Based on these observations, we propose FATA, a temporally-adaptive technique for fast and accurate dynamic thermal analysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
